A major offensive by Rwandan-backed M23 rebels in east Democratic Republic of Congo appeared to have stalled on Saturday after the army took back some ground, two civil society sources and a local official said.

Rwanda-backed rebels who have captured eastern Congo’s largest city say they plan to take their rebellion to the capital and seek to gain political power.

Rwandan-backed M23 rebels say they are now in control of the key eastern Congolese city of Goma. Their fighters continue to claim more territory in one of the world's most mineral-rich territories.
